HITS estimates: Kelly 18.7k, Carrie 15.7k

Small sales declines were to be had all around among albums by Idol alums for the week on HITS Daily Double's Top 50 building album sales chart.

Leading the pack was Kelly Clarkson's All I Ever Wanted, which slipped by a miniscule 2% to 18.7k copies, and fell #21-24. Carrie Underwood was the only other alum to be featured and moved 15.7k copies of her Carnival Ride for the week, marking a #26-30 slide and a scant 6% sales dip.

Final numbers courtesy of Billboard will hopefully be available sometime later this week.
